Patent GB-834072-A (GB)
Title: A new or improved method of manufacturing electrical resistors
Inventor: KIGHTLEY ANTHONY JOHN
IPC: H01C1/14
Filed: 1957-09-09
Abstract: 834,072. Electric resistances. PAINTON & CO. Ltd. Dec. 9, 1958 [Sept. 9, 1957], No. 28397/57. Class 37. A method of manufacturing resistors comprises laying a filamentary resistance element along a carrier, or a plurality of carriers, joining leads to the element at spaced intervals to provide a plurality of connected resistors and then severing the element between adjacent resistors. In one embodiment a plurality of carriers 2 which may be of ceramic or plastic, of U-shaped section and having transverse slots 5 at the end are aligned in a groove 8. A filamentary resistance 1 (for example resistance wire or glass coated with a metal or metal oxide) is laid along the channel, and leads 3 are placed in the transverse slots 5 and joined to the element with a conductive cement. The leads are bent at right-angles to form two sections 6 and 7 and may be either placed in the slots with the longer sections 7 extended laterally as in Fig. 2, or alternatively with the longer section 7 extending longitudinally (Fig. 4, not shown); in the latter case, a second bend, which is subsequently removed, is made in the leads so that the longer sections extend laterally during the manufacturing process. After separation the resistors may be coated with a suitable compound, e.g. glaze, in the case of ceramic carriers. In a second embodiment (Fig. 5) a ribbon 17 formed of paper impregnated with partially cured thermosetting resin has small areas of silver paste 13 deposited along its length. The resistive element 15 is laid along the ribbon in contact with the silver paste carriers and leads 16 formed from strips of nickel are laid transverse to the tape so that their inner ends are in contact with the element and the areas of silver paste. The second ribbon similar to the first is laid on top and the sandwich so formed is cured with heat and pressure, and then cut to form separate resistors which may then be dipped in an epoxy resin. To improve thermal conductivity, the outside of the resistor may be sprayed with a metal, or the ribbons themselves may contain a material such as alumina having a high thermal conductivity. A resistor formed by this second process may have notches 18 (Fig. 6) to reduce the risk of the element shorting to adjacent components.

Patent GB-285404-A (GB)
Abstract: 285,404. Boehringer, A., (trading as Boehringer Sohn, C. H.). Feb. 15, 1927, [Convention date]. Dihydromorphine; dihydro- and tetrahydrothebaine; dihydrothebainone; dihydrothebainol; dihydrocodeinone.-Dihydromorphine is obtained by demethylating tetrahydrothebaine, which can be obtained by hydrogenating thebaine. The demethylation is effected with such agents as aluminium chloride or hydrogen halides, especially hydriodic acid, and may take place in stages. The hydrogenation of thebaine by known methods in the presence of colloidal platinum produces a mixture of dihydrothebaine, tetrahydrothebaine, dihydrothebainone and dihydrothebainol; by using platinum oxide as catalyst, high yields of tetrahydrothebaine are obtained and the working temperature can be lowered; moreover, the thebaine can be used in the form of a salt dissolved in an organic solvent. The tetrahydrothebaine may be isolated from the product and treated with demethylating agents; or the dihydrothebaine and dihydrothebainone may first be separated and the residue demethylated; or the whole product may itself be demethylated, if desired in stages. The treatment in stages is effected by first converting the dihydrothebaine into dihvdrocodeinone by means of mild demethylating agents such as hydrochloric acid, removing the dihydrocodeinone as the oxime, and finally converting the remaining tetrahydrothebaine into dihydromorphine bv means of strong demethylating agents such as hydrobromic acid. According to the examples, hydrogen is passed at ordinary temperature through a menthanol solution of thebaine hydrochloride in the presence of platinum oxide and hydrochloric acid; the tetrahydrothebaine is separated from the accompanying dihydrothebaine and dihydrothebainonetwo methods of separation being given-and boiled with hydrobromic acid solution; after distilling off the acid in vacuo and treating the residue with ether and potassium carbonate solution, dihydromorphine is precipitated; treatment with hydrobromic acid of the oily hydrogenation products left after separating the dihydrothebaine and dihydrothebainone also gives dihydromorphine.

Title: Improvements in or relating to apparatus for crinkling yarn
IPC: D02G1/00
Filed: 1955-10-07
Abstract: 792,110. Crimping yams. SCOTT & WILLIAMS, Inc. Oct. 7, 1955 [Oct. 8, 1954], No. 28654/55. Class 120(3) In apparatus for crinkling nylon or similar thermoplastic yarn, inner and outer circular sets of spaced elements presenting outwardly and inwardly facing surfaces rotate relatively to means whereby one or more yarns are fed between the opposed surfaces and relative radial movements between the sets produce overlapping of their surfaces to impart to the yarn a zig-zag configuration in which it is retained, softened by heat and then removed (optionally, with rapid cooling, as by a stream of cold air). The apparatus may be in the form of a modified circular knitting machine 2, Fig. 1, the cylinder of which is surrounded by a housing 4 (which may constitute in part the cam ring of the machine) containing an electrical element 6 controlled by a thermostat 8 to heat elements corresponding to the normal sliders and sinkers and, consequently, the yarns embraced thereby: straight yarns are fed from cones 16 via a guide 42 and crinkled yarns, which are withdrawn via a guide 62 without straightening the wrinkles by excessive tension, are wound upon cones 14 carried on a winder 12 which is driven in synchronism with the rotary cylinder from a common motor 10 therefore. In the region of the guide 42, a cam 44 successively engages butts 32 of lowered vertically slidable elements 22 to raise them to the position 46, Fig. 3, and elements 24 are retracted at 48 so that extensions 38 clear the guide 42. As the elements 24 are moved radially inwards by engagement of a cam 28 with butts 26, the incoming yarns are engaged by notches 40: the elements pass between and overlap the then fully raised elements 22 and the yarns are retained in the resulting zig-zag form for the major portion of their travel around the machine cylinder. As the elements approach the take-off guide 62, cams 60 and 28 impart movements thereto (which are the reverse of their movements at the yarn feeding stage) to free the crinkled yarn from engagement thereby. A stream of cold air is directed from a nozzle(s) 64 to cool the yarn to below the softening temperature of the material thereof. An irregular crinkling of the yarn may be produced by the apparatus shown in Figs. 9-11 which comprises the elements 24 and two forms of vertically slidable elements 82 and 84 having notches, as at 98, similarly spaced to the notches 40 and in alignment therewith as the yarns are first received and finally released, and controlled by cam races 90 and 92 opposing rise and fall 94 and 96 of which produce slight relative vertical displacement of the elements 82 and 84 which, together with the radial movement of the elements 24, produce a threedimensional deformation in the yarn, Fig. 12, (not shown). Specification 676,522 is referred to. Reference has been directed by the Comptroller to Specification 747,320.

Abstract: 1,207,915. Cooking bottled foods &c. FMC CORP. 18 June, 1968 [21 June, 1967], No. 28957/68. Heading A2D. [Also in Division B8] In a continuous apparatus for cooking a commodity hermetically sealed in a container, e.g. food in a wide mouth glass jar, the container contents are cooked by passing the container through a mixture of steam and air, maintaining the steam airmixture at a total pressure that acts against the external surface of the container with sufficient force to prevent rupture of the hermetically sealed container, and discharging streams of water immediately adjacent to but spaced from the container and at a temperature no lower than the cooking temperature to heat the steam-air mixture to cooking temperature and to cause the steam-air mixture to circulate thereby ensuring that the steam-air mixture immediately adjacent the container has a high vapour content at the cooking temperature. The invention comprises a modification of that disclosed in Specification 1,135,148 in which the streams of cascading hot water S<SP>1</SP> are not directed against the external surfaces of the containers C as in said prior Specification but merely fall adjacent thereto, heat transference being effected by means of vapour Z arising therefrom condensing on the containers C. Additionally the series of vertically disposed hot water troughs 84<SP>1</SP>, equivalent to the troughs (84) in the prior Specification, is supplemented by a second series of vertically disposed troughs 84<SP>11</SP>.

Filed: 1936-10-26
Abstract: Condensation products containing an etheric oxygenation, such as cyclic formals are produced by reacting an olefine with an aldehyde in the presence of a boron trihalide associated with 1-5 molecules of water.  Thus, formaldehyde and propylene yield the cyclic diether <FORM:0483828/IV/1> and an aldehyde R3COH and an olefine R1CH=CH-CR2 yields <FORM:0483828/IV/2> where R1, R2 and R3 may indicate alkyl, aryl or aralkyl groups.  The boron halide catalyst may be prepared as described in Specification 478,085, [Group III], by reacting a liquid halogen acid with boric acid.  Thus, one equivalent of orthoboric acid or half an equivalent of metaboric acid may be reacted with three equivalents of hydrofluoric acid to give the dihydrate of boron fluoride.  In an example, boron fluoride is passed into 37 per cent formalin, and propylene is passed into the product at 0-20 DEG  C.; the product is made alkaline and then distilled, yielding a series of formals.
